Abstract
An ashtray has a base with a lid hinged thereto. A filter is in the lid in order to accommodate an easy filter replacement. An air duct in the lid enables a fan in the base to draw smoke through the filter and out the base. The fan is operated in response to raising the lid to an upright position. The intake to the air duct is far enough from debris in the ashtray to preclude drawing the debris into the air duct. The lid tends to seal in odors when it is closed. An area in the base may also receive a filter in order to provide a compatibility with preexisting filters.
